(1) I think there is great mileage in combining the fixed-decimal concept with Martin Fowler's Quantity pattern, so that a variable could be defined as not just two decimal places but also (say) "GBP" or "USD", and it would be an error to add the two. Same applies for adding metres, kilograms and other quantities. There has also been discussion that the 'type' of a quantity should determine what math should apply.
Isn't this something that is ideally suited for implementation in a Python module, based on a core implementation of fixed decimal numbers?
I'd agree with Jack here.
Me too - I thought I said that in point 2, but in retrospect I didn't say it clearly enough :-) - Andy
